About Smith Optics

When Bob Smith, founder of Smith Optics, started building homemade ski goggles in his kitchen back in the 1960s, he had no idea his hobby would evolve into one of the most respected eyewear brands in the world. Officially founded in 1965, Bob’s fledgling company eventually grew from a small line of Smith goggles into a full array of eyewear products. Today, Smith sunglasses and goggles are loaded with cutting-edge technology, from advanced Carbonic TLT optics to PivLock interchangeable lenses, and Smith helmets are helping protect skiers and riders on the slopes. From the hiking trail to the terrain park, Smith sunglasses, goggles and helmets are the choice of athletes who demand the absolute best.
